TPS54160 2.5 MHz DC/DC Converters

TI's 60 V, 1.5 A, step-down regulator protects against 65 V transients

Image of Texas Instruments' TPS54160 2.5 MHz DC/DC ConvertersTI's TPS54160 device is a 60 V, 1.5 A, step-down regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. A low-ripple, pulse-skip mode reduces the no-load, regulated output-supply current to 116 µA. Using the enable pin, shutdown supply current is reduced to 1.3 µA.

Under-voltage lockout is internally set at 2.5 V, but can be increased using the enable pin. The output voltage startup ramp is controlled by the slow-start pin that can also be configured for sequencing/tracking. An open drain power good signal indicates the output is within 94% to 107% of its nominal voltage.

A wide switching-frequency range allows efficiency and external component size to be optimized. Frequency fold-back and thermal shutdown protects the part during an overload condition.
